Disables sysop pages.
The standard sysop pager script checks for this file before allowing the user to page the sysop. The page is denied (regardless of all other security settings) if the file exists. Creating this semaphore file does not affect existing paging sessions. In fact, your paging tool can create the file if you want to temporarily stop other people from paging you during an existing session. Be sure to delete the file when finished.
